                  <pre>Hello Bars, 

Has anyone set up Arden or a mesh network as a local wireless net through ham radio? Arden stands for "Amateur Radio Emergency Data Network". It's a way to have a wide range personal data network among hams to use in case of emergencies. I'd like to see how much interest there is in the club to make this a club project and build them together. The hardware is low power and relatively inexpensive. I'm sure we have some expertise in the club who can speak much better on it than I. Let me know what you think.
